Fault detection technique for wavelength division multiplexing passive optical network using chaotic fiber laser.

Highlights: [•] The monitoring technique is based on erbium-doped fiber ring laser. [•] The wavelength of chaotic laser can be continuously tuned to match with the channel of the WDM-PON. [•] The range of chaotic lasing wavelength can cover the C-band and L-band working region. [•] The spatial resolution is up to an order of centimeter which is independent with measuring range.
